Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
kubectl log app-pod --container sidecar
Why it's wrong here
Incorrect; the command should be 'kubectl logs', not 'kubectl log'.
- ✗
kubectl logs app-pod sidecar
Why it's wrong here
Incorrect; the container name must be specified using the -c flag, not as a second positional argument.
- ✗
kubectl logs -c sidecar app-pod
Why it's wrong here
This command places the -c flag before the pod name, which is not the conventional order. The standard syntax is 'kubectl logs <pod> -c <container>', so option D is correct.
- ✓
kubectl logs app-pod -c sidecar
Why this is correct
Correct; this uses the proper syntax: kubectl logs <pod-name> -c <container-name>.
